Ran across this from Mosso, a spin off from Rackspace. Pricing looks very attractive, and there are some interesting twists. One is that you can run PHP/ASP.Net on the same server, no problem. You can get SQL Server for another $5 a month (hosting starts at $100 and includes a lot of stuff), the only downside I saw was that they don't support SQL Agent - making it a solution that doesn't work easily for me (and because I suspect it's hard to virtualize the agent). They've online chat if you've got questions, and noticed that they support reselling as well - wouldn't take many clients to pay the $100 a month!
